【摘要】：光子晶体光纤(Phetonie Crystal Fibers,PCFs),又称为微结构光纤(Mierostruetured Optical Fiber)和多孔光纤(Holey Fibers)。PCFs和传统的普通光纤在结构上不同,全世界研究人员对它产生了浓厚的兴趣。通过前两章对概念的了解,在第三章中系统的对光子带隙型和全内反射型光子晶体光纤的传输特性进行了研究,通过利用RSOFT软件光光子晶体光纤产生的进行带隙模拟,并对其结构进行设计;并通过使用COMSOL软件对限制损耗进行仿真计算,同时利用软件对全反射型光子晶体光纤进行仿真。本文在第四章对光子晶体光纤和普通单模光纤的的耦合损耗进行计算并对传输损耗和熔接损耗进行实验测量。通过选用电弧熔接机,对HC-1550和HI-1060两种光纤利用光源和功率计进行测量,选取合适的熔接参数,将两种光纤进行熔接。结构显示,通过优化熔接参数对不同放点强度和不同放点时间熔接时产生的空气孔内部产生的塌陷和模场失配等现象对传输损耗和相熔损耗所产生的现象进行解析。
[Abstract]:Photonic crystal fiber (Phetonie Crystal Fibers / PCFs). Also known as microstructured Optical Fibers and porous Fiber Holey Fibers). The structure of PCFs is different from that of conventional fibers. Researchers all over the world are interested in it. Through the understanding of the concept in the first two chapters, the transmission characteristics of photonic bandgap and total internal reflection photonic crystal fibers are systematically studied in chapter 3. The band gap of photonic crystal fiber is simulated by using RSOFT software, and the structure of the optical photonic crystal fiber is designed. And through the use of COMSOL software to limit the loss of simulation calculation. In chapter 4th, the coupling loss between photonic crystal fiber and ordinary single-mode fiber is calculated, and the transmission loss and weld loss are measured experimentally. Through the selection of arc welding machine. The HC-1550 and HI-1060 optical fiber are measured by light source and power meter. The appropriate welding parameters are selected and the two fibers are fused. The structure is displayed. By optimizing welding parameters, the phenomena of transmission loss and phase melting loss caused by air hole collapse and mode field mismatch caused by different discharge strength and time are analyzed.
